Fluctuations in the stock market represent the changes in the national economy objectively, stock price prediction predicts the future trend of stocks using the past data, which has been widely focused on. Some machine learning algorithms, such as linear fitting and sequence mining, are used to predict the stock market. However, linear fitting faces the problem of overfitting and black relationships with historical data, while sequence mining is short in efficiency and lacks dynamic adaptations. State-of-the-art methods using attention mechanism in neural networks have shown exceptional performance targeting sequential prediction and classification. In this paper, we propose a combined LSTM-CNN attention model to explore the role of attention mechanism in Long Short-Term Memory (LSTM) network-based stock price movement prediction. Experimental results show that our LSTM-CNN-attention model can provide an accurate prediction and reliable trial on the stock price prediction, and the attention mechanism significantly improves the model performance in the stock market.

This paper provides an overview of the rapidly expanding fintech sector and its impact on traditional financial services. Fintech has emerged as a customer-centric business model in response to the shortcomings of conventional financial services during the financial crisis and COVID-19. The fintech industry has created prospects in a variety of areas, including blockchain (specifically cryptocurrencies), robo-advisors, online payment services, and peer-to-peer lending platforms. However, the quick expansion of fintech also comes with risks, and investment decisions must be made carefully, considering project duration and volatility. Risk management is crucial to preserving financial stability, and legal oversight is necessary. Machine learning and deep learning techniques can be employed to recognize and mitigate these risks. Banking institutions must take precautions to protect customer data and manage unforeseen operations. The fintech sector has the potential to transform the financial industry while maintaining long-term financial health through a balance of innovation, regulatory monitoring, and financial stability.

Currency policy plays a crucial role in macroeconomic management and is of significant importance for the economic stability and development of countries and regions.

The objective of this research paper is to thoroughly examine the risks and investment opportunities that exist within the aviation industry for publicly listed companies. The aviation industry encompasses a wide range of sectors, including airlines, aviation manufacturers, and aviation service providers, all of which play a vital role in the overall economy. Many airlines operating within this industry have shares listed on public stock exchanges, providing investors with the opportunity to engage in buying and selling activities.

The objective of this paper is to explore the correlation between the capital structure and op-erating performance of selected leading pharmaceutical companies listed on the stock ex-change during the COVID-19 pandemic. To investigate how diverse capital structures influ-ence corporate performance, this study collects, calculates, and compares pertinent financial data, including leverage ratios, performance indicators, and cash flow, for these firms over three years. The findings show that companies with lower debt ratios are more likely to achieve stable earnings and cash flows, as well as to achieve higher performance indicators to some extent, compared to companies with higher debt ratios. Thus, capital structure has an impact on a company's operating performance. At the same time, a reasonable capital structure optimization can enhance a company's operating performance and mitigate opera-tional risks. It is recommended that listed companies in the pharmaceutical industry should focus on optimizing their capital structure to reduce financial risks and financing costs and to improve cash flow levels in order to achieve stable improvements in operating perfor-mance while ensuring sound operations and management. Investors should also focus on the capital structure of companies when making investment decisions and select those compa-nies with a sound capital structure for investment. These findings and recommendations provide suggestions and directions for the pharmaceutical industry to optimize its capital structure and improve its operating performance.

Pharmaceutical innovations, including drugs and vaccines, consistently remain a top priority in development and research efforts. The COVID-19 pandemic has further emphasized the significance of drug research and development, prompting a growing number of nations to invest in this field. Governments have increased funding and introduced various incentive policies to stimulate innovation, bolstering the expansion of the pharmaceutical market. As a result, the pharmaceutical sector has evolved into a fundamental economic pillar, closely linked to economic growth, healthcare standards, and the overall well-being of the population. Consequently, economists and investors now pay greater attention to the industry than ever before. Despite the heightened focus on pharmaceuticals, the sector is not without its challenges, with numerous risks presenting obstacles for many companies. Identifying and understanding these risks, developing strategies to overcome them, and determining methods to maintain competitiveness and market share in the future is crucial for the continued success of these enterprises. This paper will focus on the WACC calculation to reckon the risks for Johnson and Johnson, Pfizer, and Roche as examples of pharmaceutical companies, put them down to contrast and predict the development.

With the global promotion of energy conservation and emission reduction in recent years, some new energy vehicle enterprises are emerging in the market. To avoid potential risks in the new energy vehicle market with over-investment, the paper selects Tesla, BYD, and Toyota as examples, and uses CAPM and WACC to calculate and analyze the risks of three automobile enterprises based on the financial data in 2022. The result shows that Tesla owned the largest WACC and risks due to the calculation, and Toyota had the smallest WACC and risks. According to the analysis of data combined with the market situation of three companies, the author finds unique risks for each enterprise and provides a feasible direction for the development of three enterprises. It shows that the development of electric vehicles, guarantee of production, good product quality, and reasonable allocation of funds can help automobile enterprises avoid risks in the future.

This paper makes an in-depth study of the US healthcare industry from both empirical and theoretical aspects of capital structure and investment value. By calculating the WACC (weighted average cost of capital) for three of the most representative public companies in the US healthcare industry (Johnson & Johnson, Pfizer, and UnitedHealth Group) and reviewing the literature, it is concluded that the company's business and capital flows have been affected due to the impact of the COVID-19 pandemic. At the same time, due to some differences in the main business and nature of the three companies, United Health Group found that it has the highest investment risk. Based on the analysis of the investment value and investment risk of Johnson & Johnson, Pfizer, and UnitedHealth Group, this paper provides more appropriate investment recommendations for investors with different preferences, to further understand the future development trend of the American medical industry.
